CONTRAST DECISIONS (measured against this palette, not eyeballed --
see the mockup file for the full ratio table). The consequences that
matter while editing this file:
1. midBrown is NEVER a text color. Dividers, disabled fills, and resting
placeholder text only (placeholders are contrast-exempt under WCAG).
2. Input borders use darkBrown, not lightBrown/midBrown -- the lighter
browns fail the 3:1 non-text minimum against both the page and the
input's own near-white fill.
3. Buttons keep the app's real green fill/text (matches Button.tsx).
4. Italic emphasis renders in darkBrown, never green, so it stays
legible at body-copy sizes.
